Don't do this.  This can lead to SERIOUS security problems.  When you
"touch" a file an empty plain file is created, yes.  However, it is created
with the default permissions specified by your umask and group.  If you
forget to chmod/chown/chgrp the file/directory you could possibly create a
security hole.

Try:

cat /dev/null > /path/to/my/file

The file ownership and permissions should remain correct.
